Verses 5, 6. - And Abraham gave all that he had unto Isaac. I.e. constituted him his chief heir, according to previous Divine appointment (Genesis 15:4), and made over to him the bulk of his possessions (Genesis 24:36). But unto the sons of the concubines (Hagar and Keturah), which Abraham had, Abraham gave gifts, - "doubtless established them as youthful nomads" (Lunge) and sent them away from Isaac his son, - Ishmael's dismissal took place long before (Genesis 21:14); probably he then received his portion while he yet lived (i.e. during Abraham's lifetime) eastward, unto the east country (or Arabia in the widest sense; to the east and south-east of Palestine).

25:1-10 All the days, even of the best and greatest saints, are not remarkable days; some slide on silently; such were these last days of Abraham. Here is an account of Abraham's children by Keturah, and the disposition which he made of his estate. After the birth of these sons, he set his house in order, with prudence and justice. He did this while he yet lived. It is wisdom for men to do what they find to do while they live, as far as they can. Abraham lived 175 years; just one hundred years after he came to Canaan; so long he was a sojourner in a strange country. Whether our stay in this life be long or short, it matters but little, provided we leave behind us a testimony to the faithfulness and goodness of the Lord, and a good example to our families. We are told that his sons Isaac and Ishmael buried him. It seems that Abraham had himself brought them together while he lived. Let us not close the history of the life of Abraham without blessing God for such a testimony of the triumph of faith.And Abraham gave all that he had unto Isaac. By his last will and testament; not all out of his own hand, while he lived, at least he reserved somewhat for himself, and for gifts to his other children; so his servant declared to the parents and friends of Rebekah, Genesis 24:35; wherefore some render the words here "had given" (d); or the sense is, that he had at that time purposed and promised to give all that he had to Isaac, and now he actually did it.
